Why you need security for your server?

[1] The Internet has created many new global business opportunities for enterprises conducting online commerce. However, the many security risks associated with conducting e-commerce have resulted in security becoming a major factor for online success or failure.

Over the past 7 years, consumer magazines, industry bodies and security providers have educated the market on the basics of online security. The majority of consumers now expect security to be integrated into any online service they use, as a result they expect any details they provide via the Internet to remain confidential and integral. For many customers, the only time they will ever consider buying your products or a service online is when they are satisfied their details are secure.

This guide explains how you can utilize Digi-SSL™ to activate the core security technology available on your existing web server. You will also learn how Digi-SSL™ allows you to protect your customer's transactions and provide visitors with proof of your digital identity – essential factors in gaining confidence in your services and identity.

Using Digi-SSL™ Certificates to secure your online transactions tells your customers you take their security seriously. They will visibly see that their online transaction will be secure, confidential and integral and give them the confidence that you have removed the risk associated with trading over the Internet.

Using Security helps you realize the benefits of online commerce:

Cost effectiveness of online operations and delivery

Open global markets – gain customers from all over the world

New and exciting ways of marketing directly to your customers

Offer new data products and services via the Web

Only if you have visibly secured your site with SSL security technology will your customers have confidence in your online operations. Read on to learn how SSL helps you achieve the confidence essential to successful e-commerce.

What is SSL?

What is Secure Sockets Layer?

[1] Secure Sockets Layer, SSL, is the standard security technology for creating an encrypted link between a web server and a browser. This link ensures that all data passed between the web server and browser remains private and integral. SSL is an industry standard and is used by millions of websites in the protection of their online transactions with their customers. In order to be able to generate an SSL link, a web server requires an SSL Certificate.

When you choose to activate SSL on your web server you will be prompted to complete a number of questions about the identity of your website (e.g. your website's URL) and your company (e.g. your company's name and location).

Private Key and Public Key

Your web server then creates two cryptographic keys – a Private Key and a Public Key. Your Private Key is so called for a reason – it must remain private and secure. The Public Key does not need to be secret and is placed into a Certificate Signing Request [CSR [2]] – a data file also containing your details. You should then submit the CSR during the SSL Certificate application process to Digi-Sign, the Digi-SSL™ Certification Authority, who will validate your details and issue an SSL Certificate containing your details and allowing you to use SSL.

Your web server will match your issued SSL Certificate to your Private Key. Your web server will then be able to establish an encrypted link between the website and your customer's web browser.

NOTE: For detailed application and installation instructions please refer to section
'Step by step instructions to set up SSL on your web server' of this guide.

Displaying SSL

Displaying the SSL secure padlock

[1] The complexities of the SSL protocol remain invisible to your customers. Instead their browsers provide them with a key indicator to let them know they are currently protected by an SSL encrypted session – the Padlock:

All SSL Certificates [3] are issued to either companies or legally accountable individuals. Typically an SSL Certificate will contain your domain name, your company name, your address, your city, your state and your country. It will also contain the expiry date of the Certificate and details of the Certification Authority responsible for the issuance of the Certificate. When a browser connects to a secure site it will retrieve the site's SSL

Certificate and check that it has not expired, it has been issued by a Certification Authority the browser trusts, and that it is being used by the website for which it has been issued. If it fails on any one of these checks the browser will display a warning to the end user.

-----

Use the name of the web server as Common Name (CN). If the domain name is mydomain.com append the domain to the hostname (use the fully qualified domain name).

The fields email address; optional company name and challenge password can be left blank for a webserver certificate.

Your CSR will now be created. Open the server.csr in a text editor and copy and paste the contents into the online enrolment form when requested.

Online Certificate

Apply online for a Digi-SSL™ Certificate

[1] Visit https://www.digi-sign.com/product/digi-ssl[6] and select your SSL Certificate product type. You will be required to submit the CSR [2] into a web form. When you make your application, make sure you include the CSR in its entirety into the appropriate section of the enrolment form. When you view your CSR it will appear something like:

Be sure to copy the CSR text in its entirety into the application form, including the:

Install a Digi-SSL™ Certificate

Step one: Copy your certificate to file

You will receive an email from Digi-Sign with the certificate in the email (yourdomainname.cer). When viewed in a text editor, your certificate will look something like:

Copy your Certificate into the directory that you will be using to hold your certificates. In this example we will use /etc/ssl/crt/. Both the public and private key files will already be in this directory. The private key used in the example will be labeled private.key and the public key will be yourdomainname.cer.

It is recommended that you make the directory that contains the private key file only readable by root.

Step two: Install the Intermediate Certificates

You will need to install the chain certificates (intermediates) in order for browsers to trust your certificate. As well as your SSL certificate (yourdomainname.cer) two other certificates, named UTN-USERFirst-Hardware.crt and Digi-SignCADigi-SSLXp.crt or
Digi-SignCADigi-SSLXs.crt, are also attached to the email from Digi-Sign.

Apache users will not require these certificates. Instead you can install the intermediate certificates using a 'bundle' method.

In the Virtual Host settings for your site, in the httpd.conf file, you will need to complete the following:

1. Copy this ca-bundle file to the same directory as httpd.conf (this contains all of the CA certificates in the chain).

Apply online Certificate II

Install the Intermediate Certificates

Add the following line to SSL section of the httpd.conf (assuming /etc/httpd/conf is the directory to where you have copied the ca.txt file). if the line already exists amend it to read the following:

SSLCACertificateFile /etc/httpd/conf/ca-bundle/ca.txt

If you are using a different location and certificate file names you will need to change the path and filename to reflect your server.

The SSL section of the updated httpd config file should now read similar to this example (depending on your naming and directories used):

SSLCertificateFile /etc/ssl/crt/yourdomainname.cer

SSLCertificateKeyFile /etc/ssl/crt/private.key

SSLCACertificateFile /etc/httpd/conf/ca-bundle/ca_new.txt

Save your httpd.conf file and restart Apache.

Certificate Classes

Different Classes of Digi-SSL™ Certificates

[1] There are four main classes of Digi-SSL™ Certificate and these are explained in the following sub sections:

The Digi-SSL™ Xs is for low/no value transactions. For corporate users and commercial websites the Digi-SSL™ Xp or higher class Digi-SSL™ is recommended. The Digi-SSL™ Xs should only be used to authenticate your site to visitors and although technically it can also be used for encrypting data submitted through the site, without the additional insurance cover offered by the higher classes of Digi-SSL™ the value of the transaction is not important.

The Digi-Sign Certificate Practice Statement [CPS][7] v3.7, Sub section 2.4.1.a and 5.32.1 both state that the maximum warranty associated with a Digi-SSL™ Xs certificate is €0.01. So if your information is worth more than €0.01 and you require warranty protection, you should only use the Xs Certificate to authenticate your website. This does not mean you can’t use the Xs for encrypting data, it only means that in the event of a fault in the Digi-SSL™, you have no warranty.

Digi-SSL™ Xp

The maximum warranty associated with the Digi-SSL™ Xp or Xg Certificate is €10,000. The Certificate Practice Statement [7] v3.7, Sub section 2.4.1.b and 5.32.2, both state clearly that this is for corporate or professional use and carries a warranty in the event of failure.

Other Differences between Xp/Xg & Xs would be that

Xp/Xg Certificates are replaced free of charge any time during their life cycle. Xs are not.

Xp/Xg Certificates provide telephone support. Xs do not.

Xp/Xg are issued with the secure Digi-Seal™ for displaying on your website. Xs are not.

Digi-SSL™ Xg ‘Wildcard’

Digi-SSL™ Xg Certificates are only supplied in specific cases where multiple hosting specifications require flexible naming within the Digi-SSL™. This specialist configuration can include multiple Common Names within the same Certificate, wildcard facilities or a combination of these requirements.

Extended Validation

Digi-SSL™ Xe Extended Validation SSL [EV SSL]

[1] Digi-SSL™ Xe Certificates are Extended Validation SSL s[EV SSLs] and were released into the market in 2007 in response to the new initiative from Microsoft® and IE7.0 where the presence of an Digi-SSL™ Xe on the server causes the IE7.0 address bar to turn green as a means of indicating to the user that the SSL is a high assurance EV SSL.

Extended Validation SSL Certificates [3] give high security Web browsers information to clearly identify a website’s identity. When a user, with a Microsoft® Internet Explorer 7, visits the website the address bar turns green. A display next to the green bar will toggle between the organization name listed in the certificate and the Certificate Authority [5] (Digi-Sign, for example). Firefox and Opera have announced their intention to support EV SSL in upcoming releases. Older browsers will display the EV SSL Certificate just as it does existing SSLs 9i.e. no discernible difference, but equally, no errors are caused).

The benefits of EV SSL are easily understood when high profile incidents of fraud and phishing scams and concerns about identity theft are considered. Before the user enters sensitive data, they want proof that the website can be trusted and that their information will be encrypted. Without it, they may decide not to do business with your site. High security browsers and EV SSL Certificates provide the assurance of extended third-party verification combined with a clear visual display that gives consumers the confidence they need to do business with you.

The high assurance SSL or EV SSL offers the website user is a competitive advantage on the internet. For organizations with a high profile, using EV SSL is the most effective defense against phishing and other Internet scams. When users see the green bar and the name of the SSL vendor, their confidence in the security and integrity of the site is naturally improved.

Digi-ISP™ Service

Digi-ISP™ Xs and Xp Service

Digi-ISP™ Service Xs

[1] The Digi-ISP™ Service is almost identical to the Digi-SSL™ Service but with one important distinction: The internet Service Provider [ISP] conducts the validations [8] process under license from Digi-Sign. Once the AACD™ Contract [9] between the ISP and Digi-Sign is signed, the ISP then has the ability to issue Digi-SSL™ Certificates to any domain it chooses.

This Service is not limited to ISPs and can include Information & Communication Technology [ICT] companies and IT Professionals that need the flexibility and convenience that Digi-ISP™ Service Xs offers.

The Digi-ISP™ Service Xs can be operational in a matter of days (depending on the level of customization required) and there is little or no training required as it has been designed so that even ‘non-technical’ people can easily understand how to use it. Combine all of the above benefits with the built-in Account Management facility for customer billing and this becomes a powerful application to any ISP arsenal of services.

Digi-ISP™ Service Xp

Digi-ISP™ Service Xp is a further enhancement of the basic service whereby a dedicated Intermediate Root in the name of your organization is created according to the SAS70 specification for conducting Root Key Ceremonies. The Certificate Practice Statement [7] [CPS] and Certificate Policy [CP] that you agree with the Digi-CAST1™ Team will determine the type and number of separate Intermediate Roots your organization require.

Once the CPS and CP are finalized and the Root Key Ceremony(s) is completed, the Digi-ISP™ Service Xp can be operational within 5 – 7 days, subject to Production Schedules. The following sub sections describe this important Key Ceremony in more detail.
